Preliminary results of active centrifugal compressor surge control using variable inducer shroud bleed

Abstract

The goal of this paper is to give a short introduction to the reader into the preliminary results of the practical investigations of active centrifugal compressor surge control using variable inducer shroud bleed (VISB). After establishing the mathematical model of the VISB researches are being carried out on a compressor. There is a detailed description of the measurement equipment which covers a test bench and a data acquisition system. With the measurement and evaluation of the thermodynamic operational parameters of the compressor system, the theoretical investigation can be validated, which is also presented hereby.
